CSS3 across browsers?

[mojo13]

Hi there.

I'm getting there with my site but notice differences when comparing browsers. I built in firefox and it seems to be ok there. One problem is no radial gradient in the body on other browsers (I'm using just a background colour there). Another is the lacko Nav wrapper appearance. That is no linear-gradient. Also rounded CSS corners using border-radius doesn't work in IE. I'm trying to use -webkit- to get things to work in Opera with limited success. Can anyone point me in the right direction here?
